Stay Cool Anywhere: O2 Cool 5 Inch Battery Operated Portable Clip Fan (2 pack) - Grey Review

Bought two of these for a weekend trip and they worked great! The clamps were strong enough to hang from the walls of our tent and we were able to attach them to the backs of chairs while sitting with friends. I love them so much I'm even ordering two more for my son's tent!

Bought these for my son's stroller when we visited Disney in June. They were great life savers! They chilled him in humid Florida! The battery seemed really good, we use the fan several hours a day throughout the week and never had to change the batteries. Definitely glad we bought these fans

Just purchased and tested. The airflow is better than I expected after reading other reviews. I think it's good so far. Not enough battery life experience yet. Annoyingly, there's a screw covering the battery compartment, although it seems to close nicely without a screw. Question is, do you have a screwdriver handy when you're camping or something.

I bought these for my twin grandson's stroller, one for each size. They push a lot of air to be so small. The fan runs on D batteries, I don't know how long they will last. We've used them several times and don't see any signs of slowing down. The fan can be rotated almost as far as it will go. The clamp is really impressive. It's pretty springy. Clamps very well. I would definitely recommend this fan to anyone who needs a portable cooling source.

I LOVE these fans. I bought this from Sports Academy 2 years ago and couldn't find it again so I contacted Revain! I like this fan because it runs on D batteries, not AA batteries. New design using AA batteries and it doesn't work that well! It provides strong wind to keep kids cool while buckled in the stroller. We also use them in the height of summer when it's SO hot when you first get in the car. We can clip them to the edge of child car seats to keep them cool until the air conditioner…

We bought these fans to use on both of our strollers during our trip to Disney World in June. They worked amazingly and many people commented that they were a great idea for the 98 degree heat. They released more air than any other stroller fan I've used. They also didn't burn the D batteries like I thought. We used them every day, most of the day for a full 7 days and I only changed the batteries on the last day as I felt the air performance had dropped. They attached well to the stroller and…

For a long time I've been looking for a fan that can mainly be used for a stroller. I was very happy that I found this device and another person said it worked for their child. I would say the device is big but the fan works. I mean it gets a decent breeze and it's shabby. I was a little frustrated at first that it uses those big D batteries, but after using it I realized it will last several hours, the size is a bit of a trade-off. The clip style looks fun but can be attached to almost any…

Two D-cells create a gentle breeze off a treadmill or elliptical rack, but I wanted more. I bought two Trustfire 26650 3.7 volt 5000mah batteries. Of course, this required a charger, and the Nitecore Intellicharger i4 is one of many that work. You should be careful to get Trustfire lithium cells with a built-in protection circuit that shuts off the current if the voltage falls below 2.5 volts. This prevents damage to the lithium cell, which cannot tolerate deep discharge. The 26650 cell is…
